Within 3 days of consistently being under the influence, I experienced mild but very unformatable withdrawal:
Anhedonia, Diarrhea, Anxiety, Yawning, Insomnia, and Cravings.
I am what the the doctors have called a "rapid metabolizer" though, so I need higher doses than others that are sitting at zero-tolerance (both my firstbuse ever and after extended periods of abstinence from opiate use).
After 5 days without me stopping to let WD set in, my withdrawals achieve what most WD scales/classifications would call "moderate":
Aches, Anxiety, Piloerection, Diarrhea, Dysphoria+Anhedonia, Signifigant Insomnia, Some chills/sweats.
After 8 days I experience near full-severity withdrawal symptoms:
Body and Bone Aches, Overwhelming Diarrhea, overwhelming Anxiety, high blood pressure, recurring bouts of Piloerection (goosebumps),Hot Flashes Sweats, Chills & cold sweats, chills/sweats, near-complete insomnia. For me thr worst symptom of withdrawals, one which is very hard to to explain, is DYSPHORIA
After 12-14 days for me it's full blown full severity withdrawals. Dysphoria being the worst symptom for me... I am making about explaining opiate withdrawals' Dysphoria to non-opiate users who have never experienced it (or any sedative wothdrawal, but opiates withdrawal bing the most dysphoric, with other sedatives WD's being the most Anxiety and Panic inducing)
